WINDOW GUARD.

Application filed September 3, 1927.

My invention relates to window guards, more particularly to a window guard for the lower sash of the commonly used two-sash window, and has for its object the provision of a simple effective device of the character designated, which shall be easily and readily raised to open position and lowered to closed position, and which shall include means accessible only from the inside of the window for locking the guard in closed position.

Briefly, my invention consists of a guard for the lower part of a two-sash window, said guard having a frame and means -to raise it clear of the lower window sashwhen the guard is not needed and to lower it to closed position, together with novel and effective means accessible only from the inside of the window for locking the guard and the upper window sash againstintruders, said means being accessible from the inside only when the lower sash is closed. In my'application for Letters Patent filed concurrently herewith, Serial No. 217,364, I have shown, described and claimed a telescoping window guard together with means for locking the guard and the'upper sash of the window in closed position. In the window guard shown in this application, I employ similar locking means, but design the guard with a rigid frame, and provide novel means for mounting and operating the guard. A device embodying features of my invention is illustrated in the accompanying drawing, forming a part of this application, wherein Fig. 1 is a front elevation of a window having my improved guard applied thereto;

Fig. 2 is a sectional view taken along the line IIII of Fig. 1;

Fig. 3 is a view in'elevation of the guide means and operating mechanism of my improved window guard removed from the window frame, and showing a fragment of the guard in section; and

Fig. 4 is a fragmentary sectional view taken along the line IVI.V of Fig. 2.

Referring now to the drawing for a better understanding of my invention. I show a window frame 10 provided with upper and lowersash 11 and 12, respectively. Secured to the side of the frame 10 are guide rails 13, 14 and 16, which cooperate to form spaced-apart guides for the upper and lower sash, As is well understood, the upper sash the lower sash and its guides.

Serial No. 217,363.

and its guides are arranged forwardly of In this specification the terms front and rear, and their derivatix'cs, are used to designate parts toward the outside and toward the inside, respectively, of the room in which the window is located. The upper sash 11 has a rela tively wide lower rail 17 provided with a beveled side adapted to extend under a similarly formed upper rail 18 of the lower sash 12 to etl'ectively close the window against cold air, moisture, etc., when desired. Both the rail 17'and the rail 18 are provided with notched ends, as' shown at 21 in Fig. 4.,in order to freely slide over the guide rail 1% and the guide means for my improved window guard, which will presently be described.

My improved window guard comprises a frame 22 having secured thereto suitable guard means The guard means is shown in the draw-"mg as comprised of wire mesh, but it is to be understood thatany suitable guard means may be employed. The frame 22 is disposed forwardly of both of the window sash and slides in a pair of vertically disposed guides 24 secured to the window frame 10 as byscrews 25, shown in dotted lines in Fig. 3, so as to be covered by the guide frame 22 when the window guard closed. Secured to the lower edge of the frame 22 is a rearwardly and upwardly ex tending member 26. the upwardly extending portion thereof fitting into guides 27. The guides 27 are secured to the guide rails 14 interposed between the guide rails 13 and 16. The guides 27 are secured by screws '30 which are so positioned as to be covered by the upwardly extending member 26 when the guard is closed. The guide 27 is formed from a square tube having a slit 28 in its side to permit the upwardly extending portion of the member 26 to be raised with the window guard. The latter upwardly extending portion of the member 26 is made larger than the slit 28 so that it is prevented from slipping forwardly out of the guide.

Secured to the upper end of the member 26 is a pivoted latch 31 adapted to be turned to the position shown in Fig. 4 where it engages with a notch 32 formed onthe rear side of the'lower part of the upper sash 11 and with a notch 85 formed in the side of the guide 27. lVhen thus turned, the guard is down in closed position and the upper sash 11 is up in closed position and the two are securely held so that neither can be opened except when the latch 31 is released from the inside of the window. Furthermore, should the latch 31 be turned so to be disengaged from the notch 32, the

guard could not be raised until turned around sufficiently to clear the notch 35 whenever it is desired to raise the guard 23, the latch 31 is" turned around to'thedotted position shown in Fig. 4 where it overhangs the upper rail 18 of the lower sash 12, where upon the guard may be raised. to open position by-raising the lower sash 12. The

upper side of the guard frame QQ is provided with a latch 36 which is adapted,

when the guard is raised to open position, to be engaged by a latch 37, whlch yield ngly holds it in its raisechopen position. ,lVhenover it is desired to lower the guard to its VVhile I have shown my invention in but.

one form, it will be obvious that those skilled in the art that it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
